Session 1, Part A:
Quick Images

 Picturing, both on paper and in your mind, is an important part of geometric reasoning. You can learn the mathematics of making accurate drawings, drawings from which you can reason. You can also learn to pay more attention to the geometry you see and to visualize with your mind. This activity works best when done in groups. Go to Note 2 for suggestions for doing the Quick Images activity with a group. If you are working alone, consider asking a friend or colleague to work with you. Otherwise, print the following shapes [link] onto separate pieces of paper and then put them aside for a while. Work on something else so that you can forget the shapes. When you are ready to begin the activity, put a shape face down in front of you. Pick it up and look at it for three seconds; then put it face down. Try to draw the shape from memory. Lift the shape for another three seconds; then put it face down again. Revise your original drawing if you think it necessary. Finally, turn the shape over and compare it to your drawing. You can repeat this activity with several shapes. Quick Images Activity: Problem A1 For each image, what did you notice the first time you saw the shape? What features were in your first pictures?

 Problem A2 What did you miss when you first saw each shape? How did you revise your pictures?
